Neogamma cIOS conflict?

Hi there, ive had my neogamma playing back ups perfectly fine up till now. I wanted to play some wiiware titles but in order to get them to run i downloaded cios 37 cios 36 and cios 55.

After i done this however now my burned discs in my neogamma come up with a DVD error (1048). The discs are fine because i can use them in my friends on Neogamma perfectly fine.

I tried reinstalling neogamma but now wad manager dosnt let me install it on IOS249, i have to change to IOS250 to get it installed. It comes up with the same error witch leads me to believe that the cISO's must be conflicting?
